Completed my first transmission rebuild.

Evening all! once again I apologize for the late reply. Just giving an update. I have clocked 1,111 miles on the new transmission. This evening I drained the pan to see what is going on and how things were looking. I am uploading 3 photos.
1. The transmission pan with just the fluid dumped but the pan not wiped. As you can see the pan is very clean minus the dark marks which is the grease from the magnet. The fluid came out very bright pink with no visible particles. After skimming the pan with a pen magnet (next photo) there is some peach fuzz going on which I expected. The third photo sort of got me on the edge of concerned but again I hope it's due to it being a new build and will clear up by the next fluid change. If you look at the filter's "edge" you will see a noticeable amount of tiny "glitter" particles that have rested on the edge and center. once gain since this is my first build I am not freaking out and hope this is expected until break-in? Also the filter element was not clogged.

Once again fluid is bright pink, no burning smell, still shifting like a champ with no odd behavior. I have to wait for reassembly as my ACDELCO filter had to be ordered. I should have it tomorrow.

If you installed new bushings then you should have some glitter from them wearing in to the shafts that pass thru them. And any new hard parts installed will wear in also. Its when the chunks showup is when you cringe.....and then order a new rebuild kit.

Good job man. Lot of reading there, did you do any sort of shift kit or just go back to stock separator plate and springs? I usually do the Transgo HD2 kit whrn i do a 4l60e.

Who on earth told you that? They were lying to you or just didnt know what they were talking about. You do realize that many of the aftermarket shift kit makers supply transmission shops all across the world with parts that have been engineered to be even better than OEM parts and in many cases fix OEM original design flaws, right? These aftermarket manufacturers dump alot of money into R&D just to fix car and truck manufacturer engineering screwups. Its happens so often that there is alot of money to be made and those aftermarket manufacturers have seized a very profitable sector.
Famous screwups:
GM Sunshell center hub weld/ thin shunshell steel
GM TH700R4 front seal walks out
GM Valve Body valves premature wear and seizing
GM Narrow 2-4 band
GM 4 pinion planetary...shouldve always been 5 pinion from the beginning
GM Transfer Case pump rub
and the list goes on and thats just for GM....We would be here all day for Ford and Dodge.

If you watch the Precision Transmission channel on YouTube Richard goes over all this and much more as he takes apart various transmissions including the 4L60E.
